IMPROVEMENT IN WHEELS F OR VEHICLES.

Specification forming part of Letters Patent No. 141,099. dated July 22,1873; application filed May 14, 1873.

To all whom it may concern:

Be it known that I, CHRISTIAN ANDEREGG, of Lawrenceburg, Dearborncounty, Indiana, have invented a new and useful Composite Wheel forWagons and Carriages, of which the following is a specification:

This is an improvement on the subject-matter of the patent No. 129,449,granted to me on the 16th day of July, 1872; and consists in combiningwith a wheel thus formed a metallic band or re-enforce, consisting oftwohoops or rings, united in a single casting by a series of equidistantbars or webs, of which one bar intervenes between each two consecutivespokes, so as to produce a hub whose spokes are sustained where supportis most needed, and of the smallest diameter compatible with therequired strength and durability.

Figure l is a transverse section in the line a: m, Fig. 2. Fig. 2 is anaxial section in the line y y, Fig. 1. Fig. 3 is a diagram of thehub-mortises. Fig. 4 shows two consecutive spoke-tenons detached.

The hub A with its stepped mortises G, and the spokes B with theircorrespondinglystepped tenons D, are of any suitable timber, and do notdiffer in any material respect from those described in said patents.Before insertion of my spokes, however, I now prefer to drive or forceonto the hub proper or wooden portion a band or re-enforce, the samebeing a single casting of brass, iron, or other suitable metal, andbeing composed of two similar rings or cylindrical portions, E E,united, and at the same time retained at their proper relative distance,by means of bars or webs F, arranged equidistantly from one another, andof thickness exactly corresponding to that of the portions of the hubsperiphery which separates the consecutive mortises.

In addition to and in combination'with the advantages specially incidentto my wooden wheel, as described in said patent, I now include thefollowing advantages: First, the metallic band, by embracing and bindingthe wheel where most required-that is to say, in the immediate vicinityof the spoke-mortises so greatly stiffens and strengthens the hub as topermit of a material reduction of its diamter, thus securing a neaterand more stylish article of equal strength 3 second, said band, bygrasping the front and the rear edges of the spokes at their place ofgreatest strain, adds very greatly to the endurance and stability of thewheel, and is especially valuable in maintaining the proper dish, which,in most wheels, especially those of the ligher sort, is quite liable togive way third, it enables the spokes to be driven in the most effectualmanner, without the slightest danger of bursting or rendin g the hub,the inward pressure of the band constantly opposing and compensating theoutward or bursting strain of the driven spokes, and enabling thewheelwright to bring the glued surfaces of the spokes into the mostintimate contact with their mortises, so as to constitute in effect asolid and jointless structure, as much as if the spokes grew out fromthe substance of the hub.

This combination of the webbed band with my stepped hub and spokes isbelieved to constitute a novel assemblage of parts, constitutinginvention, and one in which all the parts co-operate to produce a usefulresult: First, because the considerable bearing -surfaces of spoke andmortise, which was a leading object ofmy stepped forms, as described inmy former patent, are, by said webbed metallic band, extended andelaborated second, because to the mutual support of my stepped spokesand hub, in the plane of the wheel, is added the still more necessarysupport of the spokes in front and rear; third, because said metallicband cooperates with my stepped tenons to relieve the substance of thehub from a bursting strain; fourth, because said metallic band enablesme to drive the tenon -points into the narrow portions of the steppedmortises with impunity; fifth, owing to the external support of hubafforded by the band, I am enabled, by means of the last-driven or keyspoke, to secure a more solid and tightly-fitting junction of spokes andhub, and consequently produce a more substantial wheel, than wouldotherwise be possible.

1 am aware that metallic bands of form not greatly dissimilar to thatherein described have been employed or proposed for wooden wheel-hubs ofdifferent construction from mine and I therefore disclaim any inventionwhatever in such a band, separately considered.

I claim lhe combination of stepped Wooden hub and spokes A G B D andWebbed metallic hand E E F, the metallic band with the socket-webs belowthe periphery, so as to receive the upper shoulders of the spokes, allsubstantially as set forth.

In testimony of which invention I hereunto set my hand.

CHRISTIAN ANDEREGG.
